TU'ALL WHOM IT MAY CONCERN;

Be it known that I, Rrcrrsno T. Eamon, of New Haven, in the county of New Haven, and State of Conn'ectieut, have invented a new and useful Machine for Making-Needles; and I do hereby declare that thefollowing is a full, clear, and exact description of the construction and operation of the same, reference being bad to the accompanying drawings, and to theletters of reference marked thereon. i

Figure 1 is a front elevation of the machine.

Figure? is a horizontalview, showingthe working parts.

Figure 3 is an end view of the sharpening tool.

Like letters in the several figures indicate like parts. p

A is the main shaft, to which the power is applicdto drive the machine. It has upon it the cams C C C, (1 0 C 0,, which operate different parts of" the machine. It' is connected by the guard-wheels G G with the shaft B, which carries the cams C C, and the pulley or wheel D. E is a lever, operated at one end by the groove in the cam C while atits other end it moves the slideF, which feedsthe wire into the machine. H is a cutter, likewise operated by a cam on the sliaftB, which outsell the proper length of wire to form one needle. I I are a bed-piece, consisting of two parallclsides, with notches'or grooves a a a, 4320., upon their upper surfaces, .toreceivc the needles or blanks, so that they may lie across the two, and be firmly held in their positions 'by the bar K, which is prsseddtiw'iiilp'on them b'yt hc springs s s. This bar movcs'irr-grooves in the posts J J, so that it has a vertical play 'or motion, but is 'othcrwise hcld in its position. "M is arack, fitting, between the two parallel sides of the bed-piece, and having upon its upper -surface grooves corresponding in number and positionwith those upon the upper surface of the bed-piece. This rack M has both a'vcrticaland horizontal motion. The vertical motion is given to itv by thcc nhs'G G which act upon the levers N N, which are connected with the under side of by the pieces 0. The; rack M is held down firmly upon these levers by the spring in., The horizontal motion is given by the cam C,, whichdrives the rack backward and forward by means of the connecting-link P. Q Q, are revolving cutters for sharpening the noodles; They consist of a piece, 0, one end of which is attached to the spindle by which the cutter is turned, and the other and is provided with a small hole,d, to admit the needle. The two ends are left circular, and the intermediate part is cut away, as shown in the drawings, and the sliding-piece b is iptroducd and held in its place by a dove-tailed groove, into which it slides. This sliding-piece b has its surface roughened or cut, and is placed across tholinc of the needle, and at a slight angle to it, so that when the blank is pushed into the hole (Z, and tho cuttcr revolved, the point of the needle is sharpened. These cutters are advanced toward the bed-piece which holds the needles, and also withdrawn, by the lever T, which has a fulcrum ate, and is connected with the cam C, by the bar U. V is a punch for forming the groove at the eye end of the needle, byincans of the dies ff. This punch or press is operated by the lever L and com 0,. Wis a punch 'for forming the eye of the needle, bymcans of the dies 9 g It is operated by the lever L and cam 0,. X is a punch for shearing oil the extra metal at the end of the needle after the eye is punched, which is done by means of the dies h It. Thc uppcr die is connected directly to the lever L which is operated by the com 0,. Y is a frame, carrying a milling tool, 2',- for finishing theeye end of the needle. This tool has a groove, K, for a'bclt, by which it is rapidly revolved. It is advanced and withdrawn at the proper moment by the rod'L, and the com 0,. The rod L, is connected with the part Y, and the whole moves forward and backward in slides or grooves in the stationary part 71, which is, attached to the frame of the machine; The sliding par t Y is held up to the pain by a spring, at.

.The operation of my invention is as follows: The wire of which the needles are to be formed is taken from a reel in any convenient position, and is fcd into the machine by the feeder F, being'cut oil into the proper lengths by the cutter H. The blank is received in one of the grooves a,upon the bod-piece I I, and is moved forward through the machine by the action of the rack M, as follows: In the drawings the rack is shown in its extreme backward or left hand, and in its lowest position. From this position it is raised up vertically, by-the action of thc cams C, and (3,, until it is suilicicntly high to lift the blank out of the groove in the bed-picce I It thenmoves forward, under the action of the cam C the length between the grooves a carrying the blank with it,.whieh is held down by the bar K, pressing upon it from above. When it has arrived at the next groove the rack is released by the cams C (l gend drops back to its lowest position, depositing the blank in the nert groove in the bed-piece to where it started from. It remains there while the cams finish their revolutions, and the rack returns to its first position. It is then picked up again and carried forward as before. At the instant Y the blanks are d e esited in the rooves 0 osite the cutters Q Q these last are advanced b the lever T, and,

P 5 PP Y revolving rcipidl'y, sharpen the point of the blank, the operation being partly performed by Q and finished by Q. When the blank arrives opp osite'the punehV, this descends under the action of the cam 0 and by means of a. properly-formed die, makes the groove in the head of the blank. The blank then passes on to .the punch W, which punches the hole for the eye. When it has passed along to .the punch :X, the head'of the blank is sheared and trimmed by proper dies, taking off the extra metal which has been spread out by the two previous operations. When the blank arrives opposite the milling tool 2', that advances by the action of the cam C and turns and finishes the eye end of the needle. When finished the needle is thrown ofi at the end of the rack.

Iiam aware of the patent granted to O. O. Crosby, March 7, 1865, for improvement in machinery for making fish-hooks, and I do not claim any device or combination of devices shown therein; but what I do claim as my invention, and desire to secure by LettersP-atent, is

1. The combination of the cams C 0 C 0;, C C C 0., and the levers L L L N N, E, T, and U the feeding mechanism F, the cutter H, the feeding reek M, the bar K, the sharpening tools Q Q the punch V,

the punch W, the shearing-press X, the and milling tool Y, all constructed and arranged substantially as specified, the whole forminga machine for making needles, as herein set forth.

2. The sharpening tool Q Q constructed substantially as hereincleseribed.
